TOP 10 SPACE YOUTUBE CHANNELS 2018

Today, we discuss the possibility of humanity being alone in the galaxy or perhaps even the greater universe. We consider just how improbable our existence is by evaluating both the number of potential sites for life within our galaxy alone as well as the probability of abiogenesis occurring elsewhere. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://youtu.be/yyVJkbUbzxY Music: “Cylinder Five” by Chris Zabriskie “Cylinder Eight” by Chris Zabriskie “Stories About the World That Once Was” by Chris Zabriskie

Over the course of this show, we’ve talked many many times about the Transit Method for detecting exoplanets. It is simply the measure of a star's decrease in brightness as the star passes through our line of sight. This once difficult measurement has now become commonplace and can even be done with advanced amateur astronomy equipment under a reasonably dark sky. From this measurement, we can infer a few things about the planets passing by: we can get an indication of its size and if we measure several transits, we can get the period of the orbit around the host star. We can also get an estimate of the period and eccentricity of the orbit by the width of the dip in the light curve. But there is another, even more difficult measurement we can make using transit telescopes that are an important tool for learning about planets around other stars: exoplanet secondary eclipses.

Our solar system exists in a giant bubble of dust and gas in space, and researchers at the Harvard-Smithsonian Center for Astrophysics have just mapped its magnetic field for the first time. This new research is part of a larger effort to better understand the nature of superbubbles and our cosmic neighborhood.

A majority of modern astronauts experience any one of a suite of symptoms scientists collectively call Space Motion Sickness, or SMS. But despite knowing about it for nearly as long as humans have gone into space, we still don't know exactly what causes it, or how to predict which astronauts might lose their lunch.
